Adjusting the rear shocks

Hi all: I need to adjust the rear shocks as the previous owner has them set very stiff. I am confused about a few things. The service manual says to turn the adjustment plate towards the jam nut to increase the preset load and away from the nut to relax the load. Can some put this into clockwise / counter-clockwise. Also, this seems counter intuitive as turning the plate away from the nut (clockwise) would turn the plate in thereby compressing the spring????

Second, how hard is it to turn the adjustment plate. When I tried to turn it the entire shock housing rotated, not just the plate. Is this correct? It seems to me they should move independently. I sprayed some wd-40 on the plate just in case the plate the outer housing are fused.

It was pretty stiff turning the plates. Keep an eye on the shaft and make sure it doesn't turn. In my owners manual, it says 1 turn out for 165-220, 2 turns for 220-275, 3 turns for 275-335, 4 turns 335-395, 5 turns for greater than 395. This is for a 2011 FLSTF. I weigh 210 and turned mine out three turns. It's a decent compromise for me alone and when my wife rides. Good luck!!

Forgive this stupid question, but then you say "x turns out", from what are you measuring? All I see is a the threaded shaft with no markings. I have no idea where the shocks are currently set.

It is just the opposite of what seems logical.
On the Softail, the longer the shock gets the firmer the setting. When you look toward the front of the shocks, the more threads you see the softer the setting.
HD sends all the Softails with the shocks set at their softest setting, which means you should see approximately 3 to 4 threads showing.
My complete shock always turns when I adjust the shocks. I painted a white stripe on the bottom of each shock running fwd/aft so I can count how many full turns I do to each shock. It is fairly important to have both shocks set the same.

Instructions:
1. Determine whether your suspension is too stiff or too soft for your liking. Take into consideration whether or not you will be riding solo or 2-up most of the time.
2. With a white paint pen, put a mark on the face of your adjuster plate at the 6 o’clock position. This will be your starting position. Do this to both shocks
3. While holding the adjuster plate in place with the spanner wrench, break the adjuster nut free from the adjuster plate by turning the nut counterclockwise

If you are adjusting for a heavier weight (stiffer ride):
A. Continue to turn the adjuster nut counterclockwise (the nut will move towards the front of the bike) until it stops.
B. Now using the spanner wrench, turn the adjuster plate counterclockwise no more than 4 complete turns. Count the number of times the white mark crosses the 6 o’clock position.
C. While holding the adjuster plate in place with the spanner, tighten the adjuster nut up against the adjuster plate by turning the nut clockwise.
D. Now repeat the exact process with the other shock.

If you are adjusting for a lighter weight (softer ride) :
A. Now using the spanner wrench, turn the adjuster plate clockwise no more than 4 complete turns. Count the number of times the white mark crosses the 6 o’clock position.
B. While holding the adjuster plate in place with the spanner, tighten the adjuster nut up against the adjuster plate by turning the nut clockwise.
C. Now repeat the exact process with the other shock.

Note: - When you turn the adjuster nut - only the adjuster nut should turn.
- When you turn the front nut - only the front nut should turn.
- When you turn the adjuster plate - the canister might turn too. Some people find it easier to turn the adjuster plate and the canister at the same time.
- If the canister turns or not - it doesn't matter - the canister does not affect the outcome.
There are a limited number of threads. Count the number of threads visible
Use the "rule of thumb" chart below:
- 4 threads = Preloaded for a softest spring (<180 lbs)
- 3 threads = Preloaded for a softer spring (181-237 lbs)
- 2 threads = Preloaded for a softer spring (238-293 lbs)
- 1 threads = Preloaded for a stiffer spring (294-349 lbs)
- 0 threads = Preloaded for a stiffest spring (>350 lbs)

Thanks. But I do need a clarification. What point of reference are you using when counting the threads? The only real point of reference I can think of is to spin the jam nut fully forward until it stops and then count the threads from the nut back to the adjuster plate.
